ROTARY BDTTOh/l OR GRATE APPLICABLE TO FURNACES, 8&0.

SPECIFICATION forming part of Letters Patent No. 399,797, dated March19, 1889.

Application filed February 4, 1888. Serial No. 262,975. (No model.)

To all 1071 0711 it may concern.-

Be it known that I, WILLIAM J. TAYLOR, a citizen of the United States,residing at Chester, in the county of Morris and State of New Jersey,have invented certain new and useful. Improvements in Rotary Bottoms orGrates Applicable to Furnaces, 00., of which the following is aspecification.

My invention relates to improvements in the construction of a bottom orgrateapplicable more particularly to furnaces for gasi- :fying fuel formaking heating gas or corn verting solid fuel into gaseous fuel, andsuch as is generally designated as a gas-producer.

The principal object of my invention is to provide a bottom or grate ofcomparatively simple construction for supporting the fuel, and withmeans connected therewith for permitting of the free passage anddischarge of a volume of air or steam and air by forced or natural draftdirectly into the combustionchamber of the producer, and the grate orbottom actuated by simple mechanical means, whereby all ashes, clinker,or other non-combustible matter may be readily and effectuallydischarged either intermittently or continuously therefrom over theouter periphery of the bottom while the producer is in full operationand without the slightest interference therewith.

The nature, together with the characteris tic features, of my inventionwill be more fully understood by reference to the accompan ying drawing,which shows a vertical central section through a portion of a gas-generating furnace of my improved construction, with the improved rotarygrate or bottom therein, and the means connected therewith for admittingan d discharging the air or steam and air directly into thecombustion-chamber of the furnace.

Referring to the drawing for a further description of the invention, Ais a brick foundation for supporting the producer.

B is a cylindrical metal casing supported onthe foundation A andconstituting a chamber into which the non-combustible material isdischarged from the combustion-chamber of the producer. In this casingis provided a door, I), in order that access maybe had to said chamberfor removing the accumulating non-combustible material therefrom.

C is an annular plate with a flange or rim around the outer peripherythereof, and this plate is mounted on the casing 13 of the ashchamber.

D is the main shell or casing supported on the plate C.

E is a cylindrical metal casing mounted on the plate C, but separatedfrom the main casin g or shell D by means of a rectangularshaped bar, 6,and the space between the cats ing E and the surrounding shell D formsthe chamber f. Into this chamber f water is admitted by means of a pipe,f, having a stopcock, f and near the top of the main shell I) (notshown) may be provided an overflow-pipe and cook.

G is a sight-aperture in the metal plate having a removable cover, g,and which is provided for the purpose of making an examination of theash-chamber for whatever purpose may be desired.

H and H are peep-holes arranged at suitable distances apart in the mainshell and eX- tending through the casing E of the combustion-chamber,with removable stoppers h and 7t. Thes peep-holes are provided for thepurpose of readily ascertaining the dividing.

lines between the ash and the more or less incandescent fuel, wherebythe attendant in charge may determine with accuracy when to grind downthe accumulating non-combustible material. over the periphery of thesupporting-lmttom, to be presently fully described, and in order thatthe best and most economical results in the making of gas may always beinsured.

I and I are eyes depending from the metal plate C for the reception ofagitating-bars t and 1?, introduced through the casing 13 and the eyes Iand I for causing the non-combustible material supported upon the bottomwhen the same is rotated to be discharged more rapidly in one place orpart than another over the outer periphery of the bottom, as hereinaftermore fully described.

Inthe brick foundation A is mounted a elbow, j, suitably securedthereto, and to the upper portion of the elbow j is fitted anipple, j.Into the foundation A is mounted a metallic base-plate, 7' with acentral opening therein, and on this plate is mounted a capplate, 7'secured thereto by means of bolts f. The cap-plate 7' is preferablyprovided with ascrew-threaded opening, to which the vertical section ofthe blast-pipe J is secured. The vertical blastpipe J has mountedthereon a collar, 7' held to place by means of a setscrew, 7' Around thevertical pipe J is fitted, in any suitable manner, a sleeve, J, havingan annular flange or plate, j, formed, preferably, integral therewith,and this sleeve held in proper position on said pipe by means of thecollar The sleeve J extends upward into the combustion-chamber E of thefurnace, and this pipe is provided with a deflecting-hood, It, held asuitable distance from the sleeve J by means of bars 76, secured to theinterior surface of said hood is and sleeve J. This deflecting-hood 71:has an annular opening in the top thereof, and above the same, at asuitable distance therefrom, is located a cap, Z, held in position bymeans of bars I.

M is a circular solid bottom, either with or without a narrow rim aroundthe outer periphery thereof, and which bottom is secured by means ofbolts m and nuts m to a flange, j, formed, preferably, integral with thesleeve J. On the underside of the bottom M is provided a rack, m andwith this rack meshes a cog-wheel, n, mounted on a horizontal shaft, 0.This shaft 0 is held in bearings in a bar, 19, secured into the casing Band extending horizontally across the ash-chamber. To the outerextremity of the shaft 0 is attached a crank, r, for actuating the sameand thereby imparting a rotary motion by means of the cog-wheel n to thebottom M for discharging the non combustible material supported thereonover the outer periphery thereof into the sealed ash-chamber beneath,While the making of gas is uninterruptedly going on.

In an application for a patent filed by me under date of February 13,1888, and serially numbered 263,818, Ihave shown and described asupporting-bottom of the type illustrated in my present application; butin that case the invention relates to the art of converting solid fuelinto gaseous fuel, and hence such bottom has not been claimed therein.

Having thus described the nature and objects of my invention, What Iclaim as new, and desire to secure by Letters Patent, is

In a gas-producer, the combination of a vertical blast-pipe, a collarheld to place on said pipe, a sleeve encircling said pipe and having aflange, a solid bottom rigidly secured to the flange of said sleeve, andmeans, as described, for rotating said bottom to cause non-combustiblematerial supported on said bottom to be discharged over the peripherythereof, substantially as shown and described.

- In witness whereof I have hereunto set my signature in presence of twosubscribing witnesses.
